Hello, I've been trying to receive a Downlink packet from lorawan with no success. (It works with ota and transmit hough) I tweaked the code from github.com/Snootlab/lmic_chisterapi/blob/master/src/OTAA_JoinAndTransmit.c to adapt the ABP method. I notice that after the transmission, the event is not swtiched to TX_COMPLETE though the Gateway sends a downlink.

Following is the code that I used; kindly let me know if there are any obvious errors;thanks.
